I'm joining with DeAnne to share my favorite picture books to teach math concepts...
Inch by Inch by Leo Leoni- I read this book to my students when I am transitioning from measuring using non-standard units to introducing measurement using inches. We discuss why the inch worm is might be called an inch, and how so on. I love the illustrations am a huge fan of Leo Leoni so its a win win!
Tally O'Malley by Stuart J Murphy a few years ago one of my students put this book on her reading log and I asked her to bring it in. I fell in love and ordered my copy ASAP. It is perfect for introducing tallies to kids!
Even Steven and Odd Todd by Kathryn Cristaldi I think I got the name if this book from Cara Carroll over on The First Grade Parade. My kids loved it and I felt is was a wonderful way to introduce and practice evens and odds.
I use all of Welcome Books Money Matters books before introducing each coin. The kids really enjoy them and they are a favorite during read to self once I put them in our class library. I also use the Coin Counting Book.
So those are my top three books, or at least the few that I can remember right now. I have a whole basket full of picture books and such that I use during my math lessons. A couple weeks ago Reagan Tunstall posted pictures of her collection and there were so many good books I had to put in my cart! So I agree with DeAnne about my amazon cart getting full once I read other people's suggestions.
